The Influence of topography and vegetation canopy on the deposition of atmospheric particulates Studied with 210Pb and 137Cs soil inventory measurements
(University of Edinburgh, 2003)
Naturally occurring radioactive isotopes of 210Pb and 7Be in the atmosphere, plant material and soil have been used to investigate the transport and removal of atmospheric aerosols from the atmosphere by precipitation and ...

This thesis examines the interaction between woody plants, elephants and other browsers in a semi-arid savanna in northern Botswana, southern Africa. Particularly I studied how woody plants respond to herbivory, how browsers ...
Effects of site preparation for afforestation on soil properties and greenhouse gas emission
(The University of Edinburgh, 2009)
Forest plantations in the UK are often established on seasonally waterlogged peaty gley soils which often require site preparation (drainage and mounding) to lower the water table and prepare planting positions. Substantial ...
Determinants of herd productvity in Botswana: a focus on land tenure and land policy

Current state and updating of heat and moisture production of poultry and their housing systems
(Iowa State University, 2002)
An extensive literature review and comparative analysis of heat and moisture production (HP, MP) of various poultry types (layers, broilers, and turkeys) and their housing systems indicated that total heat production (THP, ...
Herbaceous plant and soil nutrient patterns along grazing gradients of the hard veld and sand veld areas of Botswana
(University of Botswana, 2005-07)
Vegetation changes associated with grazing by domestic livestock have been studied throughout the major grazing savannas of the world. Changes have been documented to differ from area to area depending on stock composition, ...
